REDOX REACTION
number of phenomena, both phtysical as well as biological, are concerned with redoxreaction. These reactions find extensive use in pharmaceutical, biological, industrial,metallurgical and agricultural areas. The importance of these reactions is apparentfrom the fact that burning of different types of fuels for obtaining energy for domes-tic, transport and other commercial purposes, electrochemical processes for extrac-tion of highly reactive metals and non-metals, manufacturing of chemical compoundslike caustic soda, operation of dry and wet batteries and corrosion of metals fallwithin the purview of redox processes. Of late, environmental issues like HydrogenEconomy (use of liquid hydrogen as fuel) and development of ‘Ozone Hole’ havestarted figuring under redox phenomenon.

Miscellaneous Examples In order to determine the exact or individual oxidation number we need to take help from the structures of themolecules. Some special cases are discussed as follows:
(I) The structure of CrO5 is
O O
O O
Cr||O
From the structure, it is evident that in CrO5 there are two peroxide linkages and one double bond. The contributionof each peroxide linkage is –2. Let the oxidation number of Cr is x. x + (–2)2 + (–2) = 0 or x = 6 Oxidation number of Cr = + 6.
(II) The structure of H2SO5 is H O O S
O
OOH
From the structure, it is evident that in H2SO5, there is one peroxide linkage, two sulphur-oxygen double bondsand one OH group. Let the oxidation number of S = x.
(+ 1) + (– 2) + x + (–2) 2+ (–2) + 1 = 0or x + 2 – 8 = 0 or x – 6 = 0 or x = 6
Oxidation number of S in H2SO5 is + 6 .
Oxidation State as a periodic property :Oxidation state of an atom depends upon the electronic configuration of an atom i.e. why it is periodic properties.(a) I A group of alkali metals show +1 oxidation state.(b) II A group or alkaline earth metals show +2 oxidation state(c) The maximum normal oxidation state, show by III A group elements is +3. These elements also show +2 to +1
oxidation states also.(d) Elements of IV A group show their maximum and minimum oxidation states +4 and –4 respectively.(e) Non metals shows number of oxidation states, the relation between maximum and minimum oxidation states for non
metals is equal to (maximum oxidation state – minimum oxidation state = 8).For example sulphur has maximum oxidation number +6 as being in VI A group element.
Paradox of fractional oxidation number :Fractional oxidation number is the average of oxidation state of all atoms of element under examination and the structuralparameters reveal that the atoms of element for whom fractional oxidation state is realised aactually present in different oxidation states. Structure of the species C3O2, Br3O8 and S4O6
2– reveal the followingbonding situations :The element marked with asterisk (*) in each species is exhibiting different oxidation number from rest of the atoms of thesame element in each of the species. This reveals that in C3O2, two carbon atoms are present in +2 oxidation state eachwhereas the third one is present in zero oxidation state and the average is + 4/3. However, the realistic picture is +2 fortwo terminal carbons and zero for the middle carbon.

Oxidation :(i) Addition of Oxygen(ii) Removal of Hydrogen(iii) Addition of Electronegative element(iv) Removal of Electropositive element(v) Increment in oxidation state of Electropositive element(vi) increase in (+) ve valency or decrease in (–) ve valency of a substance takes place called oxidation.
Reduction :(i) Removal of Oxygen :(ii) Addition of Hydrogen(iii) Removal of Electronegative element(iv) Addition of Electropositive element(v) Decrement in oxidation state of Electropositive element(vi) decrease in (+) ve valency or increase in (–) ve valency of a substance is called reduction.
Oxidising agent (oxidant) and reducing agent (Reductant)Oxidising agent or OxidantOxidising agents are those compounds which can oxidise others and reduce itself during the chemical reaction. Thosereagents in which for an element, oxidation number decreases or which undergoes gain of electrons in a redox reactionare termed as oxidants.
Reducing agent or ReductantReducing agents are those compounds which can reduce other and oxidise itself during the chemical reaction. Thosereagents in which for an element, oxidation number increases or which undergoes loss of electrons in a redox reaction aretermed as reductants.Ex. KI , Na2S2O3 etc are the powerful reducing agents.
Oxidation number change method :-(method of balancing redox equation)This method was given by Jonson. In a balanced redox reaction, total increase in oxidation number must be equal to totaldecreases in oxidation number. This equivalence provides the basis for balancing redox reactions.The general procedure involves the following steps :-(i) Select the atom in oxidising agent whose oxidation number decreases and indicate the gain of electrons.(ii) Select the atom in reducing agent whose oxidation number increases and write the loss of electrons.(iii) Now cross multiply i.e.multiply oxidising agent by the number of loss of electrons and reducing agent by number of
gain of electrons.(iv) Balance the number of atoms on both sides whose oxidation numbers change in the reaction.(v) In order to balance oxygen atoms, add H2O molecules to the side deficient in oxygen. Then balance the number of
H atoms by adding H+ ions in the hydrogen.

Sol. Let us first solve this problem by writing thecomplete balanced reaction.3BaCl2 + 2Na3PO4 Ba3(PO4)2 + 6NaCl
We can see that the moles of BaCl2 used are 32
times the moles of Na3PO4. Therefore, to react with0.1 mol of Na3PO4, the moles of BaCl2 required would
be 0.1 × 32 = 0.15. Since BaCl2 is 0.5 mol, we can
conclude that Na3PO4 is the limiting reagent.
Therefore, moles of Ba3(PO4)2 formed is 0.1 × 32
= 0.05 mol.Hence, (D) is the correct answer.

V = 170.4 mLHence, (C) is the correct answer.
